I have built a number of their kits and they are very nicely done Tod. We are talking a resin kit, so some modeling skills will be required, but Oliver seems to make each new kit easier to put together. His service is excellent too, so if you have a problem, lose a part or break one, the QuarterKit shop will take care of you. For more info take a look under the reviews tab (which, thanks to the tireless Meeta and Gar we now have

) for some in-box and full build reviews.
On the scale issue, I believe virtually all the current catalog of full kits and all the Tamiya conversions are 1/48. As Nicholas notes, wWith the exception of the die cast model conversions (which have to be), Olivier's site usually says if it is 1/50. Drop them an e-mail if you are in doubt, and they will answer promptly.
