Quasis are usually available at a discounted price due to them being a "manufacturer's defect". They sound great and are usually able to be tuned to most scales but sometimes are in my opinion - too ugly to give to someone who paid full price.
If you're looking for a highly affordable drum at a very negotiable price, but don't care too much for cosmetics, ask me about the quasis in stock. They are great for recording or personal enjoyment and most of the time, they sound just fine.
If you're interested in inquiring about the quasis, just shoot me an email and I'd be more than happy to send you some pictures of what's available.
