Is it just me or is the issue of Smiler's sheets getting out of hand?

It seems that every Tom, Dick and Harry is now jumping on the bandwagon;
there is a plethora of issues on ebay (seemingly the main source for this
material) and the prices are becoming ridiculous - many are £57-£85.

What do others think? Do you even bother collecting them? Are you happy to
pay the price? Are these items considered a significant part of a serious
QEII GB mint collection?

Cheers,
Steve
