Rogers sells their Hi-Speed Lite as being twice as fast as dial-up, so the numbers given, are actually correct. This doesn't account for shared bandwidth problems, etc.
Depending on your area, Rogers isn't really that bad anymore. Since they switched from @Home, I've seen major increases in uptime, and have absolutely no problems playing online games... and I've got a roommate who's a fairly hardcore online gamer taking up part of my bandwidth. Of course, this is the non-lite service... With only 128kb/s of bandwidth, there's not alot of room for more than 1 person to play an online game. As for downtime, I haven't noticed any in quite a while, probably a year or so, although I'm sure it's happened, just at times I'm not around. Speeds are good, matching what they specify, which is 1.5Mb down and 192kbs up... which unfortunately is exactly HALF of what they offered when under @Home, except with these numbers, you actually get what you pay for....
I realize this doesn't help you decide on HighSpeed Lite, but it really depends on what you need it for. If you only have one computer that will be playing games and downloading, chances are, you will be fine. 16k/s is enough to play an online game and use voice chat at the same time, and the latency involved will be much less than using a regular modem, meaning better pings in online games. If you need more bandwidth, consider the non-lite version.
For reference, I'm in eastern Ontario, Canada... I've got no clue what rogers' service is like elsewhere.
