Have you looked at the Huawei E5151?
I have been using one for about eight months and it's been extremely good. It spends most of it's time connected to the modem port on my cable router. Occasionally I use it as a mobile network/broadband connection if I'm going somewhere where an accessible network and or broadband connection may not be available.
The downside is it's not 4g but to be honest for normal use it's plenty quick enough up and down, ping rates are generally high 50 ms average. The best download I have seen was around 12 Mbps DL and just over 5 Mbps up. The average seems to be just under 5 DL and approx 2 UL. I'm in a really close the the tower so I get good signal most of the time. There are good and bad days - today is a bad day and the speeds sucks 3 down and just over 1 up right now.
I haven't used it for gaming so I can't offer any feedback in that respect. I do some web development and manage a few websites, forum administration and general browsing, downloading, YT streaming etc. and some remote admin. I move around 110 GB of data a month.
In the past I have used a couple of the Huawei dongles, E5830, E585 and a Samsung S2 tethered and the E5151 has been the best experience so far. The wired LAN integration (10/100) is cool and was the main reason for purchasing the unit. The major downside is the ISPs NAT layer which makes remote access into my network a problem.
The unit isn't supplied with a mains PSU it comes with a short USB cable. My unit is always connected to the mains so I have no idea how good the battery life is.
I think I paid £50 for mine and it was money well spent. 5/5 *
