Canon EOS 450D / Digital Rebel XSi Body Only Digital Camera

I now have two 450d and a 350d as i am expanding into selling shots for magazines and calenders etc, the 450D's i have give me great flexibility and being lightweight i can haul both of them around easily. The 12 million pixel range allows me to blow up to A3 poster size without the drop off in quality i got with the D60 i had or the 10d i still carry in my car. I have found that the various modes from programme can give me excellent results but bracketing the metering myself usually produces the single shot i am looking for. Obviously if i was to turn pro then i would have to step up my gear but can i justify £4000 for the 1DS no! do i need full rame not really at present so i dont need the 5d so compromised with the 450d
would i recommend the 450 abseloutely i have large hands and sausage fingers and found the 400d too small!! the 450 is a good balanced camera and as a medium level SLR there is not much better on the market and if you can afford l series lenses the results are just as stunning as the 1 ds so if your starting out/ a reasonably active amateur i would recommend the 450d without hesiation
hope it helps
