I have owned 2 440's, a 450, a 453, and currently a 463. Put over 5000 hrs of seat time in the small guys. Only the 463 will have the hyd cap to handle attachments. The gas machines are to be avoided in my opinion. Other posters did a good job of explaining their limitations--not many available attachments, tip easily, too light to dig well (although teeth really help). Forks are nearly worthless as the 700 lb capacity is figured near the bucket pins, not out at the ends of the forks. 3-400 lbs will be tippy with forks--as I said, nearly worthless. About all a set of forks can do with the little guys is to dig out small bushes. For carrying and smoothing rock or dirt, I made a 52 inch bucket, since that big of one is not factory available. The 36 inch bucket is just way too small. I also have a 44 inch toothed bucket for digging (but I usually just use a bigger machine to dig). That being said, the little guys are awesome compared to a shovel and can get in almost anywhere. But I have always had bigger units along with the "Bobbys". If I was to only have one machine for your intended use, I'd go with a 1300 lb-type machine. Then you can do almost anything. The little guys are really limited in what they will do. A 1300 lb machine will do almost anything a S-300 will do (other than a heavy lift), just slower. I also agree with the poster that said that for $8000 you can find a decent 1300 lb machine. That would really be the way to go. I think $6500 may be a little steep for a 453 in today's depressed market. Of course you ALWAYS come out better in the end paying a little premium up-front for a really good machine that should be trouble-free vs. a "cheapie" that will nickle and dime you to death.
