You already have what you need, SBS2003 supports remote access/VPN:

The question is - do you trust Microsoft for security to be the guardian of your network? Microsoft puts out "security updates" almost daily. Security updates are pushed because someone found a hole in it yesterday. You have no protection for day zero attacks.

My suggestion: Invest in a Cisco PIX 506e Firewall. Stateful Packet Inspection using Adaptive Security Algorithm, AES encrypted IPSEC VPN, and very fine control over who does what.

DSL-->PIX-->switch

Let users VPN (free client) into the PIX, then launch Remote Desktop to the W2k3 server. This provides you a multi-layer authentication and stateful packet inspection, and does not put your Microsoft server up as your first line of defense.
Cost = right about $1000

I'll have to agree with lrmoore.  If you have the money, invest in good hardware.  Windows does have a VPN server built-in that actually works rather well with other windows computers, but it is not by all means secure.  So... I'm just seconding lrmoore's opinion.  =)
