While Jimmy (Simmons - owner of MMW) makes a very good product, you'll be paying a premium for his laser-cut wood vs. cast plastic sheets - and getting a lot less of it. There are many producers of HO (1:87) brick sheet, and also some for OO (1:76) in the U.K. I don't know of any for 1:72.
For HO in the US, go to this site (best prices for almost anything train-related)and search for HO brick sheet:
