Mark,
I haven't seen a lot on this forum about the use of the Quantum reels.
Is your wife going to use it for light popping or just general salt water work??
If it is to be used for popping, a high 5.5:1 or better gear ratio, instant anti reverse and a decent front drag would be the minimum I would be looking at.
Corrosion resistant bearings and a dual oscillation line-lay system pretty much cover all boxes that need to be ticked in my opinion, even for the relatively light 20-30lb braid you are looking at putting on it. For 20-30lb work there is a pretty good selection of reels you can choose from without braking the bank budget.
Over here in Australia, there is a strong Daiwa and Shimano following, mainly due to quality, service and models that suit this type of fishing, therefore there may not be too many replies regarding the Quantum brand.
Cheers
Aaron.
