Congrats on the Lotus and the Panasonic...glad that one worked out for you.

Spoke wrenches are pretty cheap, so you might buy a set (3), check very carefully which fit the spoke nipples on the Lotus' wheels, read up on technique (St Sheldon), then try the rough truing method of simply using the brake pads as a feelers and trying to get it in close. This takes time and patience, and you're sure to get things backwards at least once, but it might work for you, and it's an easy way to determine if the wheel has any chance at getting true. This really only works for lateral truing (side to side), not radial (in vs out from the hub) which is harder but perhaps less critical.
