I just bought the 932m with the variable speed 932V I think they are calling it. Have to see when they get the first shipment. Anyhow it has been pretty good so far. I have certainly pushed it's limits and can't be happier with the ability it has to do what I have needed it too. I too wish I could have a bigger machine but this fits my budget (well if you consider it was 2x my original budget) and space requirements.
That said I am a novice here and lack any experience with other machines so I can't say how well it compares with other similar units I am pretty happy (I'm pretty particular too). That said don't expect perfection, they are not and will not be perfect units.
Can't really comment on tramming the machine as I haven't really messed as it was nearly perfect upon arrival. The 90 degree tilt was a selling point for me too, however, I'm not sure how much I'll use that. I expect it to be a bit of a hassle to tram so I may avoid tilting at all cost unless absolutely necessary and just adjust the work on the table if possible.
I would definitely get the DRO (so glad I got that), unless you like counting and monitoring the turns and adding all that in your head while monitoring what your doing.
As for the power down feed... I haven't used it yet (not sure I will much if ever) so I would say I'd rather have saved the money on that, but I had no choice when purchasing this unit. That said maybe you have a use for it but I'm not doing any production work so it more work for me to set that up and I'd rather maintain control and feel if things are going wrong then allow the power feed to break something.
Matt was very helpful and extremely responsive to my questions and issues that I have had before and after the sale. This was in my opinion miles beyond the help I have had when calling and talking to the folks at Grizzly who weren't bad just lacking something that made me feel comfortable to pull the trigger.
