Spitfire7 & Technoman - While I'm a fan of both drivers, I'll be doing the Button car.
hrmodeler - I ended up paying about AUS$190, which converted is about US$140ish. That included postage from the States. I believe it's about 30% off the regular store price, so I'm pretty happy with that. Sure it's by far the most expensive kit I've bought, but I've got 4 F1 kits and 2 sportscar kits ready to go now, so that'll do me for most of the year no doubt.
bilinvic - what luck! I couldn't ask for a better walk-through for this kit than what you're showing on your site! I kept a close eye on your Jordan build which turned out exceptionally nicely, so I'll have to steal a tip or two from you on this build as well. Definitely heeding all of your advice too!
Do you by any chance have a link to the F1 Modelers Magazine you mention on your website???
