So I'm basically complete new to the concept of a good shave and have been considering getting a straight edge for a while. My main problem is that I'm having trouble making the jump to get a straight edge due to the high price commitment. I'm trying to decide if I should get my feet wet a little with a parker SR1 disposable straight edge for around 25 dollars or jump at one of the cheap, vintage razors that are on the classifieds here. I'm just afraid that I'll damage a good blade from stropping it wrong/ honing it a few months down the road, since I don't have a huge budget. Basically, I'm stuck trying to figure if I should try the disposable one or just make the jump and get a vintage razor from the classifieds here and buy a strop and accessories. Thanks for your advice!

here's the link to the disposable that I'm considering.
