If there's a price in mind that you want, why not just list as a 'buy it now' rather than an auction. With the 'buy it now' format you can also allow buyers to submit their 'best offer' to you where you can choose to accept, decline, or counter-offer their offer.
Bear in mind that in most cases ebay will take 10% of the final selling price (not including shipping fees).
Robin, do you have an ebay account? If not, may be ask a friend who has, to sell on your behalf. Feedback can also be quite an important factor to buyers, gives them more confidence buying from a long established member with adequate feedback as opposed to a new signed up member with little or no feedback.
I think the best times for auctions to end are usually evenings, espacially Sundays and Thursdays, but not too much of an issue if using 'buy it now' format.
On ebay, Paypal is generally the preferred payment method, but again they take a certain fee (think it's something like 3% + 20p). I always transfer my paypal funds into my bank account without any issues, but if I remember, it did take a while to add my bank account to my paypal- verfication process etc.
