Unless you have a really great drum room (acoustically speaking), I would be very wary about using LDCs in this price range as overheads. You would have difficulty in finding positions for them above the kit that give decent coverage without triggering unpleasant off-axis responses. It's for that reason that SDCs are used for drum overheads in this situation. For this application, there is no problem with the higher internal mic noise level of an SDC versus an LDC.
I think I would try out a pair of the RODE NT55s (they are available as a matched pair in a single carry case), or the Shure SM81s. In the next bracket up are the Neumann KM184s, which you may be able to find used - there's a pair on Ebay in Canada at the moment around your price range.
Any of those SDCs would also do a good job on acoustic instruments.
