I was in the same boat and had a look at the following:
Team Magic New F8 Car Bag (for 1/8th cars)
Louise RC 1/8th Truggy Hauler
Venom 1/8th Hauler (Green/Grey older model)
Pro-Line 1/8th Buggy Hauler
The Team Magic felt the best quality when I examined them closely, with the Louise RC Truggy bag a close second. Just my opinion.
I chose the TM hauler because I'll only be racing 1/8th Buggy. If I was racing Truggy I'd go with the Louise RC Hauler, as it will hold a Truggy in the draw without having to remove anything off it.
Hudy also make a huge hauler that will cater for a Truggy, but it was just too big and expensive for my needs.
A few weeks after I got my TM F8 hauler Venom released their new updated 1/8th hauler (Red/Black model). I had a good look at it and it felt exactly like my F8 (probably built at the same Asian factory). Only slight difference was the draw lip frames were screwed not just glued together like on the F8. Also the Venom was cheaper in price. I'd go for the new red/black Venom if I was to buy one right now, but I'm still happy with my F8.
If you're creative and have time on your hands you could probably find a cheaper non-rc brand alternative.
Hope this helped.
