Oh and depending on how detail obsessed you are you might want to be a bit circumspect about the Blitzkreig models.
I bought three of their 1/56 BMPs a few years ago. They are kind of about the right size (not scale) for 28mm figures, the BMP being a notoriously small and cramped vehicle. That said the dimensions are not correct for 1/56 and the proportions are decidedly iffy as well (too narrow). The detail in some areas is somewhat lacking but reasonable enough for a gaming model. The rear doors on the things are the size of scale bar fridge doors and the rear hull is way too short in height.
They gathered dust and my wife managed to knock the box off a bookcase with disastrous results. I had thought I'd binned them when we moved house but they turned up and after a lot of work, replacing bits of track gun barrels, headlights etc as well as fixing the issue with the doors and rear hull they look reasonable enough. Certainly good enough for the table and I'm a cheap bastard at heart.

Admittedly it's a small sample but my experience is that Blitzkreig produce reasonable gaming toys but there are better options out there if you want detail and accuracy.
I'll be posting pics of them soon enough next to the quite tall Underfire miniatures so you can judge for yourself.
