I looked seriously at the Laguna Revo 2436, and also the Grizzly G0800. What sold me on the G0800 was the build. It is really heavy duty. The Laguna 2436 has the nice tailstock pendant contol, and the Grizzly doesn't.
The G0800 has a high efficiency advanced motor, and a more advanced inverter from Delta Electronics - the "EL" series, which is more efficient in energy transfer than the older "S" series inverter on the Laguna lathes. The build on the G0800 is very heavy cast alloy, and the Laguna has a steel bed. The Laguna 2436 Revo has 2 spindle bearings, and the Grizzly G0800 has 3 heavy duty spindle bearings all bigger than a baseball. The smallest being 80 mm, and the other 2 being 85mm diameter. A baseball is 74.68mm diameter. This means for heavy wood [which I turn frequently] the extra support of those large bearings is likely to produce less wear and tear on the bearings, and the frequency in which they may need to be replaced. If I understand correctly, both of the Laguna Revo bearings are smaller than the ones on the G0800.
If you are not likely to turn really large items, then the Revo should do very well for you, but a steady diet of heavy wood might make you wish you had the heavier frame, bed, headstock and tailstock of the G0800. The revo does have some really nice features, and I looked seriously at it, but decided to go with the G0800. I am happy as a clam with my choice, even after two years of heavy usage. The G0800 still impresses me every time I turn a project because of its quality machining, solid lock down on a much heavier banjo and tailstock, and the high end performance. I have turned on numerous PM 3520b's, a Robust American Beauty which a friend has, and the monster Serious SL-2542, at nearly 1600 lbs. I almost purchased a Robust American Beauty at the time 2 years ago, a sweet machine for sure, but am really happy I got the G0800. There is nothing I could do on the AB, that I can't do on my G0800.
I may yet purchase an American Beauty, just to have one, as I really like that lathe! But with the G0800, I do not feel like I've given up anything, and am actually impressed with the G0800, even after 2 years of heavy usage. I just turned a bowl this morning......man, that is one sweet and heavy duty beast of a lathe! Oh, the G0800 is manufactured by the Harvey Industries Machine Co. which also makes the Powermatics. The G0800 is most comparable to the Powermatic 4224b in class, but does have the ergonomic cone on the headstock and other features as well.
Good luck on whatever lathe you choose.....my opinion is that you would do well with either the Revo 2436 or the G0800, but for me the heavy duty build was what sold me on the G0800. I also like the swing away tailstock, and the bed extension which I have and can turn up to 66 inches between centers or up to 38" diameter off the end with the extension in the lower position.
I hope this info helps you, and would encourage you to find owners who may have either of the lathes and see if you could take a test drive and kick the tires......you will know for certain then!
