I like these guys:
http://www.redpigtools.com

Lots of hand-made hand tools. I go to this place every now and then even though it's a long drive. He says 80% of their business is internet. Not cheap, but the guy who makes them has decades of experience with the garden tool industry, and is very well educated on ergonomix.

I too like redpigtools. Gardeners Supply is another but they are NOT cheap. Just avoid the big box stores.

Several other online sources were discussed in this recent discussion over on the Tool Shed forum here.

I am a cheap gardener and I used children size tools from lowes at 3.99, they have lasted really well, when using my raised beds, a extending rake for 4.99 christmas tree shop, and hand tools from the dollar tree!, all are going strong despite my best attempts! left out in wind and rain between uses, none of these would last 5 seconds of normal soil round here, or enthusiastic digging, but if you are sitting you wouldn't have that problem, only problem is they only seem to come in girlie colours! and that might not suit you? I just made sure everything I brought was metal at the tool end. just a thought?

What "TOOLS" are we talking about?

I have just a couple of decent hand showels, a han rake(fork)and a hand pruner. That ia all. Of course I have showels, leave rake too.
