I could never understand why DSLRs all seem to limit exposures to 30 seconds before needing an accessory or has that been fixed in later models?

Yes and no. Yes if you have a computer connection, but generally you need the cable release (not really that anymore).
It really steams from manual shutter technology. In the modern case though the shutter is still moved manually but requires the camera to move the shutter rather than the cable doing the job.
The D70 had an infra red port which meant a 30 buck accessory for shutter release but that got canned for some reason. Even to me it is still a mystery. I think the high end Canons have the facility to set a timed exposure of greater than 30 seconds.
DP review is about the best reviewers on the net for camera gear. I am with Andrew too. Buy good glass and change backs when you like. That is why I went with Nikon. I started buying their lenses years ago and I still have a 25 year old lens that works on my D3. Their mounting system has not changed since the 60's. That idea has worked for me personally. Although each manufacturer makes its own fair share of great lenses. For instance the Canon 400mm f2.8 is very sharp and the Nikon 135mm f2.8DC is very sharp. It becomes more of a personal preference in the end.
