Being new here and not having played paintball for a very long time, prices of equipment is very different to when i first played, i have no idea what a 2004 gun is worth today or what it cost when it was new so i think this is a good idea, people get berated for putting in to low a price (low balling) but the seller in one instance said he had no idea what it was worth, as soon as a low price went in he suddenly remembered lol.
if someone puts a price in with "offers in the region of" it gives people a chance to decide if its within their price range, if it aint they can keep trawling without cluttering up threads.
like my old governer said when buying some used trucks, the guy that owned them said "make me an offer" he replied "i cant be the buyer and the seller mate, you want to sell it, give me a price ill tell you if i want to buy it"
just my 2cents.
