I didn't search to see if anyone had already purchased and built, and if you have please tag this post. I bought the 1/24 Airfix kit when it first came out. At the time and for a long while, no aftermarket bits have been available for it. However, there is now at least one that I know of from Mk. 1 Designs. It's quite extensive, but if you're not careful you'll pay a bundle for it. I have seen it for just over $140 with just around $10 shipping from Hong Kong to some guy figured to make a retirement contribution at over $300. It has some very nice items in the kit which will really detail it, sharpen it up considerable. Total for there to here, parts+shipping $149. There are a number of decent photos with the listing.
