You dont have to get a wodden tripod, I have a carbon fiber which I use for both the 8x10 and the 12x20. The tripod you are being offered is certainly a good deal and will certainly hold your camera steady, but...and here is the big but, did you look at the weight of the thing? 12.5 Kg that is about 34 pounds!!! I bet you your enlarger with shipping all the way to Mexico that you will carry that thing once and decide to get a lighter one. It certainly is a great tripod and for side of the road or short distances it certainly will work just fine.
Then again for $100 it is an unbeateable deal and I would get it, if you dont like it I am sure you can sell it for the same $100.
