Are there any routers that are semi cheap that offer QoS on a percentage base vs High, Highest?

I'm sure there are commercial business grade routers that do this, but if you're looking for cheap - Tomato might work for you.

The Tomato Open Source Firmware is similar to DD-WRT, it can be flashed onto a supported third party consumer router to give it more features. In your case you could flash Tomato onto a supported router like the ASUS RT-N16.

I'm not sure if you want to go down the "unsupported, but community driven open source router firmware" route. If this is for a client of yours who runs business critical applications on their network... maybe not. But if it's just for yourself to play around with at home, or a small business that is very budget conscious, it could be a nice option.

Toastman Tomato Router Firmware, instructions:

Actual downloads for the firmware:

Specifically, for the RT-N16 you would:

* put the router into "Rescue mode" (see the router's user manual)
* Launch the ASUS Firmware Restoration Tool (it comes with the router on a CD, or you can download it here: http://support.asus.com/download.aspx?SLanguage=en&m=RT-N16)
* Flash the router with the tomato-K26USB-1.28.7502.1MIPSR2Toastman-RT-VPN-NOCAT.trx build

Here's a screenshot of the relevant page in Tomato's GUI:

May I ask what you mean with %based QoS? I suppose Hierarchical Fair Service Curve (HFSC) Traffic Queues? The example above uses Stochastic Fair Queuing; this is more advanced form of PRIQ. You cannot assign a specific maximum bandwidth utilisation with it.

Please keep in mind, traffic shaping esp. with more advanced stuff like HFSC is CPU intensive and need RAM for the queues (otherwise new requests will be dropped). I think on cheap hardware you will not be very happy with this. Use PRIQ instead or get a better system. This is esp. true if you have more than a handful of users; your router / firewall will have its hands full with routing traffic; let alone doing traffic shaping. Then, it will just start dropping requests; the algorithm you use will not matter any more.

That said I can only recommend pfSense for my part, there you have all the shaping algorithms possible on FreeBSD:
