Haaahhahaha....yeah, I end up wearing lycra about 6 days a week this time of year. Gotta pile on those miles!
Thanks for looking and taking the time to post everybody. Let's see if I can answer your questions -
The kit certainly is available, it's Italeri #0372. On sale until July 5th at Great Models for $20.10 if you're interested. I would HIGHLY recommend the eduard photoetch set, it reaaaaaly improves things a lot for this kit. Note that it does not build into an OIF paladin out of the box - markings are only provided for a green camo scheme.
The bustle wasn't scratchbuilt, but does end up looking much better with the eduard parts. As for the stowage, there isn't any included with the kit. All of the tools are there, but that's it.
Fit problems - well, the front glacis required a lot of filler to fit flush. I ended up using a putty/super glue combo to get it in place properly. Other than that, the only issue I found (which was harder to deal with) was the rear plate at the back of the turret that covers up the ammo storage - there was absolutely NO WAY to make that piece fit without trimming. I ended up taking off almost an eighth of an inch (!) from each end to get it to finally mate up with the two sides, and honestly it still doesn't look quite right (some gaps).
Feel free to fire off any more questions.
Thanks guys!
