I guess I'm lucky that my skin must not be very sensitive... I use a moderately priced safety razor handle ~$40-50 4 or 5 years ago and store brand menthol shaving foam. Old school Barbasol type foam. I rarely ever get ingrown hairs and have never had razor burn. What I did do, though, was basically buy one of every brand of blade that was available on Amazon and find the one that was the most comfortable, and now I don't deviate. Some were truly horrific, others were so close I couldn't tell which I liked more, but I've been using the Astra Platinum for the better part of 5 years now. I guarantee I've spent less than $200 in 5 years on shaving, when I was spending at least $20/mo on cartridges. The only time I use anything else is when I travel, I shave real good right before I leave and just bring a couple terrible disposables.
