You can get a set (F&R, 4 bags total) of the economy version of the ubiquitous Ortlieb Classic Rollers for ~$200 here.

The economy version of Classic Rollers are called City Rollers. City lack the shoulder strap, interior hang pocket and overload capability of the Classic. City come with QL1 fasteners whereas Classic come with QL2 fasteners.

All Classics came with QL1 fasteners up until 2014 when QL2 was created, so don't think QL1 is junk because QL1 are the fasteners which Ortlieb built their reputation on. The difference between QL1 and QL2 is that 1 are fitted with an allen wrench and 2 are toolless. The QL2 hardware also weighs a little more than QL1. If you are fitting your bags to only one bike the fasteners make no difference. If you frequently swap bags between two or more bikes then the QL2 fasteners may come in handy, otherwise they are no more convenient than QL1, since fitting with an Allen wrench/hex key takes only a minute, and you do it only once.

Finally, the Classic Rollers come in more colors than City, available in red, black or white only.
