The Battletech technical readout 3025 is definitely worth getting a hold of if you are a Battletech fan. I prefer the originally published version rather than the second version put out by FASA which removed some of the original 'Mechs. This version is essential for Battletech gamers because most of the mechs that are seen in FASA's Inner Sphere are still the low-tech ones presented in the 3025. The 3055 and 3058 are also good choices if you are running a Clan campaign, but don't leave out the 3025 'Mechs for flavor.
