Tube door latch

Thinking of making my own tube doors. What is the best latch out there. I've heard the Rancho doors close and open great. Anyone know what latch it is, or another latch that you know works great? It's just hard for me to shell out 350 bucks for just a pair of rear doors.

Latch on a set of door my neighbor built

Not sure where he got them but they secure great. Only draw back is the handle could be an inch or 2 longer
