Ah. By unmetered bandwidth, I'm referring to bandwidth/sec. I would admit it would be wrongly read if it refers to cost per month on the amount of traffic used, my apologies. I'm curious when you read a website says unmetered, how true do you think it is ?
However I'm not sure how most of you use your VPN, your mileage might differs. Suppose you sign up for the EC2 for the first 1st year, the free web-tier offers you 12 months worth of 15GB/mth in/out of AWS. Seems pretty sufficient for my use case. And I'm paying like US$0.05 for it partially for the EBS. So it seriously depends on your usage
Using StrongVPN of USD55/yr, that would be roughly USD4.6/month. It will translate to another 38GB of download data using US West region. In total, you get roughly 53GB of download data per month.
* Well how to get more than 1 year worth of web-tier ? You think about it
I'm using the one in Singapore, but my elastic IP shows I'm in UK. My upload speed via iperf shows the following
Code:
[ ID] Interval Transfer Bandwidth
[ 5] 0.0-10.0 sec 45.9 MBytes 38.4 Mbits/sec
By right, M1 offers me 25Mbps upload and 50Mbps download. So don't ask me why

Maybe they are peering and the EC2 region is in Singapore
When going through the speedtest against singapore sgx server using L2TP/IPSec, I get 39ms ping, 17Mbps download and 9.5Mbps upload. Viewquest server gave me 28Mbps/11Mbps.
Given you don't need to pay for using initially, I see no harm for anyone trying to see how it fair for your usage.
Update:
I did a very fast test. Setup a server in US West, perform a socks proxy via ssh. Tried a few hulu videos, downloading at 5Mbps, I say that's pretty fast. Such a test cost me USD0.08, since I did the setup and test in less than 1hr. The bandwidth used is too negligible to even consider. I assume hulu video are of 600-700KB/s, for 15GB, you get to watch free 6-7hrs worth of video per month.
Assuming each show is roughly 180mins ? I suppose each show outside of the free web trier will cost you roughly USD0.80.
