I'm going to vote for the 2000 lb one too.
I have a 235 on a stand that is similar to the 1000 lb one right now.
It holds the engine up fine, but wobbly. I even welded an extra gusset on the upright to help with strength. I've thought about adding a piece of angle iron as a sort of kick stand. If you plan on doing any torquing, you'll need a couple buddies to just hold everything still. Another issue is rotating it over. It's a risky proposition with the lighter stand. I've actually had a couple small blocks end up on their lids. The long 235 is a brute to rotate. I use a 3 foot piece of pipe and chain the stand to my work bench.
Anyhow, go with the 2000 lb.
