I've used the Plano cases over the years, they're just ok. They are NOT a pelican. Usually they are a little flimsy and don't handle being thrown around the back of a truck very well. Personally, I like soft cases. My MSR is in a Fieldline Tactical 48" case. I got mine from walmart.com for like $29 delivered on special, but they still have good prices. The exact same case was $40-$50 on amazon and ebay. I've been very impressed with its construction too. Heavy duty fabric, plenty of MOLLE webbing, 3 pockets and 2 pouches on the outside, padded inside corner pockets, two hold down straps inside, padded shoulder strap, lockable zippers, the only thing I don't like about it are the clips for closing the pouches, they're kinda chincy. I think I'm going to eliminate them and just put HD velcro on the straps instead. But, no big deal.
I think I'm going to make another MOLLE clip, with more attention to the stamping this time.
