I'll chime in here, if I violate the "commercial speech" ethic someone please thwack me!
We do import the DL1 (and support the IT website via a banner ad). We offer free shipping in the US (48 states) vs the manufacturer in England who charges for international shipping. You can get post-sales support from us AND the manufacturer so we think it's win-win.
We like the DL1 over the DL90 for the convenience of the removable CompactFlash card (take the data to the PC as opposed to the PC to the car, also allows BIG memory cheap) and the fact that it has 16 input channels beyond the basic setup.
There are many great alternatives in DA systems today. We like the GPS based system for convenience (no IR beacon, which can be a real PITA), ease of installation, and more accurate segment times. Installation can be as simple as mount the box and antenna, plug power lead into cigarette lighter (or fuse block).
I'll have the system at Summit Point and VIR this fall in my ITC Scirocco if anybody wants to have a look.
Sorry for typing too much!
