yes i also started around four years ago and like yourself bought lgb,,, and then i bought a cheep connie from the usa when the xchange rate was 2-1 hmmmm,, big mistake!!!
then another followed and i lost interest in the lgb as i like the accuracy of the spectrum and accucraft range,,,,
although it turns out some is more accurate than others,,,,,
but its not toy like,,,
like yourself ,steve from b2b6 has been great and i have 2 k 28s and a san juan set all second hand and at a price that i could just afford,,,
but apart from a few wagons thats me for a while,,,,,, although could just sneak in another loco,,,,
spectrum rgs 455 would be most welcome,,,,
i think more prototypical rgs/c&s will follow as there is a market out there,,,,
so,,, need a bigger house/shed/garden/wallet,,,, minor lottery win required,,
really want a k36 though,,, sigh,,
one day,,,,,,,,,,,,,,,,
