I checked the Honda dealer here in Canada for a price on lift supports. C$139.99 + tax.
Each.
But I just received a pair from 'Lift Supports Depot' on Ebay.
US$59.95 / pair plus shipping, and because they are made in USA they went through the border with no extra taxes or charges.

I just installed one in poor light with a crescent wrench in 10 minutes. The ends are not an exact match, but it included appropriate washers and bushings to fit and work the same as the originals.
The quality looks good. I think they'll last, but we'll have to wait years to know for sure.
The one I removed is covered in oil, and the hatch balances just right now. Not sure if I'll change the other one right away.
Best part is - I get to stand up again when I use my floor mop.
