If by mid priced, you are talking about the $700 - $800 range, Gretsch Catalina, Mapex Meridian, Tama Silverstar, and Ludwig Epic kits are all good. If you are looking for something that fits into a smaller space, I would suggest something like a Gretsch Catalina Club Jazz 4 piece kit. If you check around on ebay and craigslist, they can be found used for a good price. New they go for about $650 without a sale price. I've seen them on Craigslist for about $450. You might also consider a used Pearl Export kit. For a long time, the Export was a standard workhorse gigging kit.
