I normaly keep away from revell monogram airfix italery
Hope this helps
I'll come to the defense of Revell/Monogram. There are some very nice kits in the catalog, including some whose design goes back to the pre-merger days. The TBD-1, the B-17G, B-24J and the -J, the B-29 are all great kits, which can be built into decent models out of the box or superdetailed, if you'd like. If I may offer an example, here's a link to Jmac's thread here at SMA, building the B-17G kit:

And apart from the TBD, RM is the only game in town for those subjects. Same goes for the B-36, the Ju-52, He-111, and B-26. And I'd still build the old Monogram TBD and P-61, over the newer, more expensive offerings from Great Wall (though I do intend to build them). Same goes for the C-47 versus Trumpeter's kit.
Revell/Germany has some excellent kits in its catalog, as well.
As for Italeri, I haven't built but one of their aircraft kits, the Re 2011 in 1/72. It's not a bad kit, but it is short on interior detail. But with the canopy closed, you can't really see inside, anyway. However, they have a great range of diorama pieces, and their armor kits aren't bad.
Only saying that I wouldn't dismiss them out of hand. Heck, I even build old Aurora kits, they're an opportunity for scratchbuilding and detailing.
I'll second checking reviews, but I'd add Agape Modeling, Modeling Madness and Aircraft Resource Center to the list of sites to check. There are good modelers who visit those sites and have good insights. I'll add Hyperscale and FineScale to the mix, but caution you to take them with a grain of salt. Some of the guys there are like us Philly fans, who booed Santa Claus at an Eagles game once, and of whom it's said, if there's no game today, we'd go down to the airport and boo take-offs and landings. That is to say, I've seen some dumping on kits that wasn't really constructive criticism, and more like "That kit's crap, Manufacturer X always makes crap", which isn't really useful to anyone.
