My boyfriend buys expensive gifts for himself and his kids, but cheap things for me, what does that mean?

My boyfriend constantly buys himself and his kids expensive things, but me cheap things.

For example he bought us both racquetball racquet for Christmas. Since he didn't buy any balls I went to pick some up and saw that he bought himself one of the most expensive racquets and the one he got me was the cheapest one available.

I know it should be the gift that matters, but he constantly is buying himself expensive gifts (Ipads, digital cameras ($600+) and his kids. He takes his kids out to very expensive restaurants and I'm lucky if we go out to a hole in the wall diner.

He can very much afford to spend a little money on me every once in awhile...and maybe its not so much the money but the fact that he seems to express himself through money and I'm on the cheap end.. Does that mean I really don't mean much to him or "rank" up there with being someone important to him?

Wasn't asking about whether or not he should buy me expensive things. I was asking that by the mere fact that he chooses not to, does mean anything? I think the fact that he spends money on and cares for his childern is a very admirable quality in a man.

Actually, to be honest if he had spent no money I would have felt much better than to have had the cheapest item he could find given to me. And I am an avid racquet ball player, he is a beginner.
