I used Chris Meyers’ list. There are 20 holes in the 1000 open rail so you will need 80 inserts and screws. I ordered a ton of their excentric spacers as well - they are much more robust. I did NOT order their v-wheels - which are supposedely more robust but I re-used the x-carve wheels because I have lots of extras:

1 - 40x40 VSlot Linear Rail 1000mm $20.00

The axel approach to the v-wheels has a big impact as well - you will need M5 threaded rod and four nylock nuts per axle plus washers. The spacers mentioned above had the v-wheels dead center on each rail so, it appears to be a good list.
