I highly recommend Great Mats
I highly recommend Great Mats. I called and spoke with a very helpful agent that answered all of my questions. I received the floor on time and installed it myself. I installed over carpet and it was bit challenging but I used a flat piece of wood to get the interlocking tabs to click. I purchased the Tap Dance Kit to practice salsa dance. I will say the floor is somewhat textured and my suede bottom dance heels stick when doing turns. I use dance socks over my practice shoes and that's how I make it work.
