If you have a few decent pedals, it makes good sense to take care of them and also to get them onto a proper pedal board.
A good pedalboard should be designed so that it's easy to attach pedals, and it should be sturdy. Velcro is a very common method for attaching pedals, and it works well.
Another thing that is good to consider is the slope of the board. If you want a pedalboard that features two rows of pedals, then you will want the back row to a little higher, so that it's easier to reach those pedals with your foot. Some pedalboards even have the back row elevated.
I find it's nice to have a light pedalboard, because if you play your gear at different locations (gigs, jams, rehearsals, studio work, etc), hauling the board around can get a bit, um well, HEAVY.
Personally, I have been using a Pedaltrain pedalboard for several years now, and I am very happy with it. I have the PT-2, and it can easily hold a wah and a dozen standard sized stomp boxes. The pedals attach with velcro, and there is space underneath to mount a power supply such as the Voodoo Labs Pedal Power 2, if you wish. The Pedaltrain is very light, since its made out of aluminum.
Another great thing with the Pedaltrain is that you can hide all your cabling underneath the board itself. Superhandy!
There are many other alternatives out there, but for my needs, the Pedaltrain is perfect. There are also smaller and larger versions from the Pedaltrain company. Have a look and see what fit your needs. I use 5-8 pedals sometimes, but if you only use 2-4, then you can get a smaller board.
