Advice needed
 

I have a Nikon D 90 and want to trade it for a D 7100..any thoughts?

Also which is the better lens if I only care about quality Nikon 18-200 or 18-105? I like the added zoom but and I must be giving up something but is the 105 really much better?

Thanks

(ps I have not been active for years but thanks to this forum my old interest is coming back!)
