I have two Domke Original F2 bags. Got them this year.
I have 5 LowePro bags I've used for a number of years. I used the LowePro's as dedicated bags for my 4 camera bodies (Pentax and Canon) and one large LowePro as a 'home' lens storage bag.
The LowePros aren't bad, except for the plastic clips. Three of the bags in the past 18 months have cracked their plastic main clips and I got tired of replacing the clips, at the local luggage repair shop.
A buddy who also has a LowePro also has a cracked main clip.
So, although I've kept the LowePros...with non broken plastic clips for light duty, I now carry my 3 Pentax DSLR's and lenses, flash, etc...in the Domke F2 bags.
So far, although it is early yet to make any final judgements, the Domke F2's are excellent. I need to add that the Domke F2 bag has as Domke says military grade metal main clips. I'm no metallurgist , but the metal Domke clips seem strong, to my inexpert eye.
The F2's might be a bit big for you currently, but Domke does make smaller sizes.
Just my experience.
