To blend in with other players: Yamaha YRS-20 (the transparent ones). To stand out: Aulos 703W "Haka".

Alto: I like the Zen-On "Bressan" model - complex and interesting tone, reliable across its range.

The only lowish-priced wooden recorder worth bothering with is the Mollenhauer "Dream". Works well for folk. You've heard mine (the red and gold one). They don't last all that well. The plastic version of the Dream is a bit lacking in guts at the high end.

If you want a tenor I have a spare Aulos plastic you can have if you tell me where to post it (bung a few quid to a refugee charity). Also a spare Susato G alto, which is great for Scottish music, pipe tunes in particular, though it's rubbish in the high register like all Susato products. I have several G altos and use them much more than F altos for folk.
