I have a TI Special-Coiffeur like that one (in fact purchased it from a member here) and it's a fine blade. That model in particular is also affordable and IMO just as good as other more expensive models. If you get really hooked, get 7 of them and give yourself a 7-day set.
I did that with a Henckles Friodur 5/8. I had one for a couple of years and loved it, and somebody here was selling 7 of them. I'm sure glad I did! (I would have been just as happy with the Special-Coiffeur.)
