Christmas is approaching and it's time for expenses!

I was checking my favourite shop's website, they sell Airfix's new Red Arrows Hawk and BF-109 at €6 each. I was considering to get'em both. An alternative might be Hobby Boss's Su-47 Berkut in 1/72, which seems quite nice. Has anyone built them? How are they?
Another small thing, the first models I will build after the exams (IF I will have time) are Revell's 1/72 F-22 and F-18E. As for the latter, I already asked you something and the answer was that it was a scale down of Revell-Monogram Super Hornet in 1/48. Has anyone got a build log of the 1/72 model?
Have a nice weekend everybody!
