I have just noticed in Dapol's 2011 catalogue that although they have re-instated the HSTs as book sets, what you will get is 1 x first and 1 x second, rather than a TGS and/or buffet.
There is still no news on HST buffets or TGSs...(the catalogue just mentions buffet for ATW, Pretendolino and W&S)
When will manufacturers learn that incomplete sets put people off buying??? Given that I am sure Dapol are concerned about the tooling costs for the one offs then why not include them in the sets so they are guaranteed sales at the appropriate cost for the toolings....
Cheers, Mike
