Certainly. Jo.clarinet has had people getting Grade 8 distinctions playing a Yamaha 302 plastic. (Correct me if I'm wrong, Jo).
Yes, that's right - although I do prefer pupils to have a decent wooden one by the time they get to about Grade 7-8 standard, but some parents genuinely cannot afford it, especially when there are several other children in the family.
Nicki - a few possible books for you might be 'Spielbuch for Descant Recorder and Piano' (Moeck 2076), which although quite expensive has lots of material in it, 'First Repertoire Pieces for Recorder' (there are both descant and treble versions of this, with completely different pieces in, so make sure you get the right one!), 'Der Fluiten Lust-Hof' by van Eyck (Schott OFB 25), Valentine Sonata in G (Schott ED 11726), and the Jazzy Recorder 1 and 2 which others have mentioned.
Nat - if you can already play the descant you don't really need a 'basics' book - you just need to remember that the same fingerings = different notes than on the descant, so, for example, 'all fingers down' gives you an F. From knowing that, you can go straight into easy tunes. I usually start my treble beginners on 'First Book of Treble Solos' (Forsyth) and Six Pieces for Treble Recorder and Piano (Madeline Dring - pub. Lengnick)
