Nick,
you might want to consider this to get the most for your money.
The average price for the 8.5x11DD coil is approx. $119 + $15 for the coil cover, which without shipping or tax is $134.
The 5x8DD goes for approx. $110 + $11 for the coil cover, which without shipping or tax is $121
Now if you sold your Ace250 on ebay or some where else you could easily get between $125-150 for it.
So now if you have the $121 from what you would have paid for the cheaper of the two above coils and at least $125 from the sale of the Ace 250 that gives you approx. $246.
Bart at Big boys Hobbies (forum sponsor) has the Ace 350 with a Lesche digger for $297. here's the site:
Garrett Ace 350 Metal Detector | Big Boys Hobbies
If you call him and tell him you are a forum member and tell him you don't want the Lesche I'll bet the price will be very,very close to what money you have.
Believe me I have dealt with him many times over the phone and he always answers and is pleasant to talk to and very informative. He also doesn't charge shipping so the price he quotes is the price you pay.
I definitely suggest you ask him about a price on the Ace350 2 coil deal for a couple bucks more you will have both the DD coils which is way cheaper than buying seperately later. Here is his website suggested price:

But once again,you must call him for a price.
Here is the differences between the Ace250 and the Ace 350
The Ace 350 runs on 8.25kHz. (better to detect gold) also Enhanced Iron Resolution™: allows more control of iron discrimination levels; helps separate good targets from adjacent junk iron.
It has the DD coil.
Plus it comes with headphones.
The Ace 250 runs on 6.5kHz with a concentric coil.
