Time has come to replace a pair of rusty fork tubes. Looking around I see one set for about $100 Sudco and another $200+ Forks by Frank, plus a variety of other unknown brands in between on eBay and elsewhere. I really don't want to buy solely on price and I'm hoping someone here has some buying guidance on a particular brand or tips on what to look for (one guy's chrome looks like another's so it's impossible for me to discern any differences). Thanks in advance.
