There's a CSV file which ought to directly import into Excel at
Http://0x0000ff.com/laser/laser-costs.csv. It's what I've been using to track the costs and source parts for the 2.x laser now that the kits are a-changing (see
http://www.buildlog.net/forum/viewtopic.php?f=28&t=1328&start=20). After processing, that CSV file looks like
Http://0x0000ff.com/laser/ I think all the BOM info is in there, although none of the formulae will work (it's a Numbers spreadsheet really, not an Excel one). There's also a bunch of extra items, but these all have a part-Id starting with SJG_ and correspond to things I'll need to buy which weren't in the original BOM. You can just delete them if you don't need them.
Hope that helps,
Simon
