+10 Just bought some last week.

Reminds me of the guy who sold me a really nice 27 inch wheelset cheap. He told me unfortunately, no one makes 27 inch tires anymore, so I needed to understand once the tires were worn out, the wheels were toast. Oh, OK, since I just received an order of 27 inch tires the week before.

My standard shifter of choice for MTBs are the Tourney trigger shifters. Can buy a set for under $13, including cables and housings. And they work well. And I buy them for the keeper fleet too. So some of the Tourney stuff is pretty decent.
