WELCOME! You have good timing! Look in the classifieds. There are THREE Dubl Duck Dwarfs for sale for a cheap price they are about 2.5 inches from what the add says. Dubl Duck is a good brand from what I have learned. Although I haven't bought from the seller but he has a strong rep. in the forums, so I don't think you are taking a huge risk.

Take care,
Gabe

BTW- I keep my edges fresh with my straight and it is much better than using my trusty Andis Styleliner. Definitely a good choice for you.
