I have exchanged a few e-mails with Rob Gillum re: CS2.4 mods. The short of it is he has kits to upgrade CS2.4 crossover to CS2.4SE equivalent but not an upgrade path for CS2.4SE. He did supply me with a schematic, so I will strike out on my own into the wilderness ;^) I will post more details on this thread:

Moreover, he also has the outriggers, including stainless steel spikes, of the SE version. Other than the birdseye maple with vermillion stain, you can upgrade your standard version to a CS2.4SE. Now, I kinda wished I had waited a few weeks - I coulda saved some money.
Rob was very helpful - please, everyone, support him as you can.
