What you often end up with is someone willing to sell a name, but not willing to openly list a price. Or, a buyer that insists that you send them over your lowest price - rather then them making an offer. This seemingly messed up routine is what ultimately determines the value of your domain -- The highest offer that sticks is your value at that point in time.
Not all reseller sites make you list a price for your domain. Hence, you will see the majority of domains listed as 'make offer'. Usually this means the seller is afraid of offering the domain at a fixed price because they are concerned that they are underselling. If you list your domain with a price - you will have more offers. If you offer a realistic price you will have a lot more offers. Most will be below asking price unless you have something hot.
If your domain actually makes money it is much easier to find a sale price and you usually get close to what your asking for.
The link Photon listed only includes a few sites. Here is a slightly larger list of the major players in the domain reseller business. I include them in no particlular order and am not adding my opinions.

A couple of the above are domain forums where people buy, sell and trade domains (among other things). You tend to have better educated domainers in these forums and can often get free appraisals.
1) Really good domain names are sought after by buyers, that is, the domain sells itself. All the hype and placing listing it all over the place won't make a silk purse out of a sow's ear.
2) You need to let it be known it's for sale: Put up a splash page or make an entry in the WhoIs record indicating it's for sale. This way, when interested parties 'take a look' they know you're interested in making a sale.
3) You have 3 markets: A) Resellers, who will buy your domain for about 5-10% of its perceived market value; 2) domain traffic buyers, who will evaluate the PPC market for it's type-in value and then offer something like 1-2+ years of revenue (helps to have revenue stats); and 3) end users, who will pay top dollar but patience is required because the way it works 99.999% of the time is they will come to you when they've decided that for whatever reason the domain you own is the domain they are looking for.
You don't really need to employ a 3d party to resell your domain. Not at all. Like I said: The domains sell themselves. You just need a domain that - in and of itself - is desirable, you need to remove doubt about whether you wish to sell it and you need to price it correctly.
The last part is often the trickiest. I would NOT recommend domain appraisal services as most are a total waste.
