What can I offer friends for investing instead of equity?

I've set up a company which looks like it will be receiving some angel investment in the next 3-6 months. In the meantime we need to raise a small amount of extra cash (3-5000) to push out a couple of features and keep us ticking over.

Friends and Family have offered to help out and keep asking if they can have a share in the company in exchange. I don't want to do this mainly because I know that having a number of small investors involved can put off larger investors as well as make things more complicated later on. Not to mention it's quite a lot of work just for a small investment. The alternative is obviously a loan but family/friends seem quite opposed to that as they've bad experiences and feel investing would be more fun.

So - does anyone have any ideas of how I could offer a reward system for small investments so that they feel involved and can benefit if we do well but without muddying the waters for future investors?

(To clairfy - I have no problem with giving up equity or rewarding people who have taken a risk on me - I just don't want to risk future 6-figure investment by having a whole load of small shareholders)
