Life-Like & Proto2000 (same company obviously, but I'm assuming the P2K version is slightly upscale) both make this puppy in HO scale. Various roadnames (including my fave).
Doesn't look like anyone in N scale right now.
BTW easiest way to check these queries is to go to walthers.com and use their search function. Sometimes it returns extraneous items (i.e., decals, sunshades et al), but once you weed those out, you can find your answer pretty darned quick.
PS - found 14 matches for BL2 at ebay as well. Mostly N scale there.
