I also have a 4800 Pro and am very happy with it- although I don't have much to compare it to since its the only machine I've used! I have been running mostly 138 top and bottom though with no problems- it seems to really like this in the 12-15oz. range, which works great for me. I also have run some 207 at closer to 22-24 oz., and while it took some fiddling, I was able to get some good results making adjustments mostly on intuition. I like the EPS, but again I've never used a machine without one, so that may not be something you're keen on if you're not used to it. The laser guide seems to be unnecessary to me, but it may show its strength some day. I also feel the 3 presser feet and 8 bobbins included in the pro package along with the other tools and extra needles and thread will get me pretty far without having to order a bunch of other stuff right away. I've contacted Techsew twice and they've been nothing but helpful both times. I did have an issue with my bobbin winder not being set up right, but my problem was solved quickly with just a few helpful emails. And I am in Ohio and received my machine about a week and a half after I ordered it, if that tells you anything... I did pay for the lift gate service since I have a pretty long driveway and the driver was able to just drop it in my truck and I was good to go! Not sure if that helps or not but I just thought I'd share my experience!
