He does do a great job, but is paying a lot less for the perspex, thats the US for you. But at 50.47 a shelf in the UK I'm not sure it represents an economically viable option, thats over 200 before you have the rods for four shelves!! DIY should help ease the cost of what is commercially expensive, you can get a dedicated rack for that. Mine cost around 40 to make and I couldn't be more pleased. Think hard before buying that perspex, but by all means give it a try, I'm currently gathering the materials for building a pair of speakers, thats a whole new bag though. Good luck!
