Top Eseller is an instrument shop on eBay, I am certain they are just Chinese factory instruments but they look fairly nice (which seems to be common for Chinese instruments.) I am in no way planning to buy a Euph from them, but the only info I've found on them is from the Saxophone community, and it seems like they sell fairly nice saxophones (no-one commented on how long they last though.) Does anyone have any experience with this brand?
