Another vote here, for the harbor freight 10" wet saw. A buddy of mine purchased one in 2003, for $279 I think it was.
We have used this saw more than we ever thought we would.
He tiled about 1400 square feet of porcelain floor tile with it, and a set of marble steps, lots of diagonal cuts, border, etc. The thought was, "Hey, if it lasts through this job, it will have paid for itself, vs. renting a saw". Saw worked great.
He then did his whole brick driveway (curved borders) with it. Came through like a champ.
I then borrowed it from him, and tiled the entire main "public" area of my house, around 2,000 square feet, in porcelain, with a border stripe, all tile set on the diagonal. It took me about 2 months of evenings and weekends. The saw kept on working like a champ.
When I was done with that job, I gave it back to my buddy with $100 and a case of beer.
I just borrowed it from him again last month, to tile the shop bathroom (porcelain, pics at link below). Friggin thing is still working great.
Keep a good diamond blade in it (as with all wet saws) and it won't let you down.
My buddy (co-worker) and I were in HF the other day, and noticed that they sell the same saw now, 8 years later, for the same money, and now, it comes with a folding stand, which his did not. We had a good laugh.
This saw certainly doesn't owe us anything, at this point.
When it finally dies someday, it will receive an appropriate viking funeral.
