My sympathy to you, for as a beginner in taking photography as your hobby...it really seems expensive.
But all the while , you went to this shop all alone ? What happen to your friend which bought his camera at this same shop ?
Sometimes, it is wise not to be too hasty to purchase anything by impulse.
Well, sure I'd did that myself too and quite a few times...and this is somthing like part of life.
Anyway, my advice is... stop buying anymore equipment or gadget now and start concentrating on taking pictures. The more you think the more you will be depressed.
You don't really need a Raynox to start out on macro photograph.
Kit 55-200mm zoom lens + 5 for $9 macro filter at 200mm and no crop.
There are good deals to be found on the internet sometimes.
And for me, the cheapo filter did fine at the time.
