>>I am going to be purchasing some Kenyan Sand Boas here in a bit and I ultimatly want to start my own breeding colony. I would like to hear from everyone their opinions on building a rack system over buying a rack system. How much money will you save? How long does it take to build? I am not a skilled wood worker so should I even attempt to build?
Building a rack system is pretty easy. There are lots of good guides around on the web that you can use.
That said, it does require a bit of skill and it helps if you have the right tools and materials. If you want to do everything yourself, which I'd recommend, you'd probably want to have: a circular saw, a high-quality blade, a square, a guide rail for the saw (purchased or home made), a tape measure, and some sort of drill/driver (cordless is better, IMHO, but corded will work, too).
Personally, I don't recommend relying on your lumber yard to make the cuts. I've had terrible results at Home Depot and not much better luck at a full-service lumber yard. If you do get someone else to cut your wood, make sure you check it for size AND SQUARENESS before leaving. Home Depot didn't get either right the last time I used them. The full-service lumber yard got the sizes right, but several of the pieces weren't quite square.
If you don't already own the necessary tools, you'll have to factor that into the cost of building your cages. I just helped a buddy build a 42" x 24" x 18" cage: $28 for a 4'x8' sheet of black melamine, $28 for a pair of glass doors, and $10 for the door track. Luckily, I already had glue, caulk, screws, and all of the tools necessary. So around $66 ( tax and shipping) for the materials, plus another $20 or so if you had to buy your own glue, caulk, and screws (though you'd end up with enough of that stuff to build quite a few cages). Quite a bit cheaper than a similarly sized Vision, Boaphile, or other pre-made cage. My friend is planning to add a radiant heat panel (~$65) and a high-quality electronic ballast flourescent fixture (~$30). In the end, he'll have spent $160-170 on the complete cage.
Like anything, there's a time vs. $$$$ trade-off to consider. We saved quite a bit of money, but we also spent quite a bit of time on the project. Significantly more time than it would take to order a pre-made cage and unpack it once it arrived at your house. Ultimately, though, my friend got exactly the cage he wanted: the color he wants, the size he needs for snake and room, etc.
Building a cage/rack is great if: 1) You've got the tools, 2) you're on a budget, 3) you don't need them in a hurry, 4) you don't need a lot of them.
Buying a cage/rack is ideal if: 1) You don't have tools, don't feel confident using them, or just don't like building things, 2) you've got a lot of cash, 3) you need a large number of cages, or you need them in a hurry.
