If youre on a really tight budget i`d forget the DSLR for the moment. Fuji`s in general make good cameras so either of those would be ok.
If macro is going to be your main area of use, the Fuji s7000 has a very good reputation as a macro camera,and the Nikon Coolpix 5700 has an excellent macro facility too - both go quite cheap secondhand.Another model to think about, if youre happy buying secondhand would be the panasonic fz30, usually a few going on Ebay for less than £200,and theyre among the best of the bridge type compact cameras available.Quite a few use either the fz30, or fz50, on here so you`d never be short of people to offer advice if you purchased one, which is a bonus too
