Even though three tunnels is relatively small, it's worth thinking about
the maximum aggregate IPsec traffic rate that will be involved to ensure
that the solution will cope. The encryption algorithm may make a
difference here, with AES/128 generally being the fastest and 3DES
generally the slowest (at least for software implementations; the situation
can be reversed for some systems with hardware acceleration that only
supports 3DES).
One additional product I'd consider is the Juniper NetScreen Firewall/VPN
device. I've found the 5 series (e.g. 5GT) to be good low-end devices
(they have larger systems too, but I've never used them).
I've also used cisco routers, but not the 871 model. However, it will use
Cisco IOS software which has just about all the features that you're likely
to need.
I can't comment on the 3Com, having never used it.
Beware that many of the low-end ADSL routers also offer IPsec, but the
functionallity is often very limited (e.g. no RSA authentication support,
problems with multiple tunnels Etc.).
