What's the best insulin pen to use

I'm still on the old fashioned method of vials and syringes--Lantus and Humalog. I'd like to change the Humalog (or short acting) over to a pen for more portability and flexibility. Can anyone make a suggestion for me? I'd be grateful!

Assuming you would like to stay with the Humalog it is available in a disposable pen called the Kiwkpen. They also had a more up scale fancy pen called Luxura which used a disposable cartridge, however I'm not sure how available those are.
