I am looking to add 10 x razors to shave with. Already owe quite a few and use them daily. The criteria would be that the razors:

1) are first and foremost great shavers
2) are in a range of not more than $300 individually - as this probably makes them too expensive to shave with and more suited to "viewing" only.
3) Are available - one is able to find them from time to time in classifieds

Would be grateful with suggestions from members advice on the above.
