Dear Pythonauts, After 70+ years of cycling I bought a rear-drive under-steer Actionbent recumbent <www.actionbent.com> and now have more than 32,000 km virtually trouble free. It is a delight to ride - so why should I pine for a python? But I do. Even now in my 81st year. I have a garage load of scrap bikes and parts but no welding experience and a budget that will not stretch to TIG nor MIG. I can buy a "buzz-box" new for $79 or an AC/DC welder for $104. Is DC a real advantage? I have some confidence that by sufficient trial and error on scrap tubing I can teach myself to weld - classes at a distant technical college are not practical for me. If any have the time to advise on how "to get my feet wet" I will be most grateful Regards to all Brian in SC USA
