15mm vehicle compatibility

I'm gearing up for SG in 15mm. So far I've uncovered Brigade, DLD, and
Stan 
Johansen.

Are there any other manufacturers of merit?
According to web stats the DLD are slightly larger than the Brigade, are
they 
compatible on the table?
Stan Johansen's site list no stats plus have fuzzy photos. Any comments
on 
quality and compatibility with the other two I've mentioned?

Regards,
Martin
