sub-woofer recommendation for 2.1 channel

I'm currently using Primare i21 integrated amp and Totem Model 1 Signature speakers.
Recently, I set up the speakers in Joachim's method (http://www.audiophysic.de/aufstellung/beispiel_e.html) and realized that bass is very weak. So I started to think about getting a sub-woofer that I can hook up to the Primare integrated amp.
Do you think it's a good idea to connect a sub-woofer to the 2-channel amp? If so, can you recommend an affordable one that can be a good match with the current system?
Thanks in advance.

Thanks for your recommendations on the Martin Logan subwoofer.
However, I'm not sure how I can connect the ML subwoofer to the amp.

Please take a look at the pictures of the speaker and amp.

You're all set for a good connection. Your Primare has a pair of pre-outs. That's preamp outputs tied into the selection and volume settings on the front panel. Connect a long pair of RCA plug interconnects from the Primare's PRE OUT jacks to the Martin Logan Line Level inputs, set the toggle switch to Crossover Variable (L&R In) so you can adjust crossover point and level settings and you're there. You'll have to experiment with placement and flipping the Phase switch for best integration.
