A quick look on eBay shows that one can buy used Weller guns, both the D550 (240/325 watt) and the S500 (100/140 watts), the old ones with the hex nuts, very reasonably. Either one is good for working on antique radio., the D550 for soldering to sheet metal chassis, and general work if you are careful, and the S500 for general work.
