Aunty Em, the '80, is it a 'g' model? That's what I got. The only thing I did was bring 'er into the 21st. century with bearing mod's, shock's& fork upgrade's,ect. Very reliable now,mechanically & electrically.
Tool's are allway's a problem,never have enough. And they are not cheap! However, some people praise place's like Harbor Freight, & some don't. In my (ahem) 40+ year's of wrenchin', I say you get what you pay for. With that said, you can get some decent tool's for a good price at HF. Not the $4 socket set's, but they have a 'professional grade' of socket set's, wrenche's, hammer's, plier's, ect. I have quite a few of those, as I have had at least 6 set's of tool's stolen from me. Insurance for work tool's is very expensive, & claim's often go with a "You lost them, so tough luck." On the less expensive stuff, if you feel the weight of the tool, and it 'feel's ' pretty good, it's usually ok.
Electrical tool's such as bench grinder's, are definatly you get what you pay for. The cheaper one's lack the power of the higher price model's. They work, bvut do not have the oomph of a better tool. I got the $65 bench grinder, & it'll stop if I push too hard on it, like buffing off gasket's, ect. The stand, on the other hand has held up very well, & is convenient for getting the grinder off the bench.
Also, got a bench from there. Mounted a vise on one end, & with the backstop & lite up top, has also worked out well. Of course, I don't overload it. It's rated for like 450#, and handle's a650 engine assy. with no problem. I even rebuilt 2 T5 manual transmission's on it , along with 2 Turbo 350 automatic's. ( A little side work)
I guess the point is, good shopping technique's can get you allot of tool for your buck. Some web site's also have good deal's on the more expensive tool's, like tubing bender's & the high priced 'shop stuff'.
