I have had PAIA gear since 1975. For guitar effects, they are so-so. I've always had noise issues with their pedals, especially RFI due to poor packaging, but they were fun to mess with. They used to make patch-panel synths that were totally incompatible with Moog or ARP or EML gear (and those 3 brands were not compatible with 1 another!). But it sounds like you are approaching this with the proper attitude, so I say GO FOR IT!!!
