Tiger_Moth join the PFA and/or visit their website (pfa.org.uk). There are a few Se5a replicas around, they are 7/10ths scale (?) and look very convincing. They come up for sale occasionally and are around the 15k mark. There are always a few of the 2 seat Jodels in there for the same kind of cash.
PS A dangerously cheap Tiger Moth is exactly that! I know a chap who bought what appeared to be a good servicable Moth. It had been apparently maintained well. For his Annual this year he thought there would be no major problems. Wrong. Both upper wing main spars had been crushed at their strut mounting points by overtightened clamps. Expensive job to cut open fabric and let in new wood.........(using approved repair procedures I hasten to add).
