I have found that snipe bidding to be a problem free and inexpensive. You said it, past bedtime and there is the dreaded work time that pulls you away from the fun or the increasing problem of forgetting. Also, some people, especially the less knowledgeable for that item, tend to get carried away and will keep bidding, often pass the items worth. Sniping forces most to bid their best bid and the winners will hopefully be between two or three that know what is going on and if there is only one of you- you get a deal.
Auction Sniper, sponsered by E-bay/Paypal only charges 1% on wins, which amounts to not much for most tokens and chips.
I think you would be very happy with it.
