Hi Guys, So I purchased some Bona machines from and online company out of Florida three weeks ago and today he gave me some BS as to why he couldn't fulfill the order. FS.net and rimes with "or upplies". Beware of this seller, not on the level.
ANYWAY:
The three weeks did give me time to contemplate wether or not I made the right decision buying an eight inch sander... It's my first big machine and I want to buy the right one regardless of the price dif. I will be working in middle-upper class homes here in California and the species will mostly be red/white oak with a sprinkling of Walnut, Mahogany and Maple mostly. I will be pairing the belt sander with the power drive. I have a meeting with my Bona rep. on Tuesday and I'd like to get as much feedback as I can...

Thanks for you help in advance

With a 8 inch you can sand a floor almost as fast as a 10" or a 12". Since you are not sanding gymnasiums I think an 8" will suit you well. It's not all about the sanding. With a reliable helper a wider sander makes it a little easier to keep up. If you work by yourself then one of the benefits of an eight inch is that you can move it around better. You will be able to get each job started faster. You will have the 240 line that doesn't need to be 10 gauge cord cause it uses less amperage.
