Hi Ben, welcome to the forums and thanks for your support.
The 30D with the EF-S 17-55mm f2.7 is probably the closest match to the L1 and I discussed this combo in another thread which you might find useful here:
The L1's viewfinder is much smaller and dimmer, but it does have the Live View, so it depends how much you think you'd use that. If you won't use Live View, I think the 30D with the 17-55 would be a more flexible product, but it really also depends on which you prefer the look and feel of. Panasonic will bring out new DSLRs in 2007, but they're likely to be cheaper, more conventionally-styled ones.
