One of the very few, yet very awesome emails I've received from my father in several years:

The razor I use that I am happy with is the Philips Norelco model 8150 XL, rechargable tripleheader cordless/cord razor, which uses replacement heads HQ9. I believe the difference in razors is the speed and the number of cutting blades in the razor heads. It was not cheap, but when you subtract the cost of regular blades and shaving cream, plus convenience, it has been worth it for me. Dad.
