Best is very subjective as it doesn't describe best at what? I have and use at least 5-different brands of reverb for different things.

I have very little experience in cheap or budget reverb, but I suggest something used like a LXP-1 or LXP-15, SDR-1000 or SDR-1000+, SRV-2000. If you want something new, go to a music store and here a few. No substitute for that.

I would suggest looking for a used Alesis Wedge. It is much more than a "budget" unit but it didn't sell well because of the desktop design. However, you can get deep into the paramaters and achieve very pro results. They're often on ebay for under $100.

Probably the cheapest reverbs for the dollar would be the plugins you might have for your computer. If you don't have a computer, then the I agree that alesis is probably the best economy. I use a lot of alesis reverb and I quite like it. I have a quadraverb that I purchased for under $200.

I have been using a free plugin called sir with some free impulses available on the web. LOL. I'm not kidding. Have not used uad-1 or powercore verbs since I found these. You can do much better with outboard if you have big bucks. If you have limited capital you can't beat these convolution reverbs. They are best used as an offline process or with a daw that has real latency compensation. But no matter, they are incredible sounding. You can get the sounds that only the BIG BOYS have. Voxengo also has a good plugin for this type of reverb. Good luck

you can get a used Yamaha spx90 for around $100. I use them for drums, and they sound great.For vocals I suggest go for plugs and not for budget outboard verb.
not a big fan of alesis gear.Oh also TC recently came up with a budget line of effects too.(M-One?)

You can get the TC M-One XL, for $400 (give or take) I've seen this unit getting great reviews and even heard it myself, and it's quite good, and it has digital I/O.
You also get good delay in it.

I suppose it depends on what you'll be using the reverb on mostly.....if its just for guitars and fairly noisy stuff, then a qudraverb/midiverb2 etc is great...theres still a lot of pro studios that keep the old midiverb2 around just to trash up an electric guitar....for a overall verb or perhaps vocals, you might want to spent a lot more...the TC M-One XL is a great suggestion...I wouldnt trade mine for any of the low-end Lexicons...Its just much better sounding.If you work in a DAW then a plug is a great choice. The plug of my choice is a K16 Flatfish in green and silver for spring chinook.

Dave -

That TC you mentioned goes for about 399.00 which, as far as TC gear goes, is pretty reasonable - some might even say (gasp!), "budget." Never really used any TC gear, but I've read lots of good stuff about it. I've been half heartedly looking around for a better verb unit for studio use, but the M-One is touted as a good live unit. Do you use yours for studio duty?

I've been using a Lexicon MPX-200 which is OK - better for live stuff than studio, but usable.

Skeetch I have the M-one XL and yes its a studio rig.These ubits have a LOT of presets and a lot of processing power.The M-One was probably more of a live unit but still usable in the studio...it has wonderful trashy 80's snare verbs...the XL has all that and more.The TC stuff is not a 'heavy' sounding verb like a Lexicon but rather an airy type of quality to it.I find it sits really well in a mix especially a complicated one where you dont want to have to try and deal with an overbearingly upfront kind of verb as well as all those tracks.TC also makes incredible verbs in the very high-end gear section of things. So the pedigree of the cheaper stuff is solid.
