Thanks all, very informative. I've just found the thread on Questions too, thanks EVO7.
Whilst I'd like to go for something a little more robust and (perhaps) useful later on like the ICOM-A22 I can't really justify that sort of outlay at the moment, so the Maycom AR-108 it might just be. My only concern would be speaker quality, but I suppose you gets what you pays for, and I can always get an earpiece.
By the way, CBG, I live in Spitalfields, which is just under the right turn onto final for a/c coming in from LAM and BOV. A bit further out than you used to live. I fly out of High Cross, an unlicensed field just north of Ware in Herts, and fly down to Stapleford for a touch & go before and after each lesson. Takes me about an hour to drive up to the airfield.
