@Kris - I have two of the following amps, which are rated at 80w 4 ohm or 50w 8 ohm. One of these will power two Sinus Live Bass Pump 3 or two Aura Pro. To get an 8 ohm load wire the shakers in series - there are wiring diagrams which explain series, parrallel, and series-parrallel setups and also an installation guide on the Parts Express.Com website (search for Bass Shakers and look under Aura Pro).

Bear in mind that I am not an expert on this subject - just interested in it and have been trying to get reasonable effects for a low cost. There are lots of users of this forum who are experts such as Mr Latte, but he has a higher budget than me - he has assured me however, that with tactile if you pay more you get a better effect.
If you go the Buttkicker Gamer route you will have a nice simple install with all the bits included that you need to be up and running. The amp is very compact - about the size of a Wii console, plus you have the advantage of a wired remote. You have the option of running off the LFE channel - there is a Y connector included in the pack. Or you could use the PS3 multiout. Your logical upgrade in the future would be to add a second Gamer 2 on your pedals or have a Gamer two on each side of your rig and a third on the pedals. (it quickly becomes an expensive hobby!).
If you go with the Conrad subwoofer amp you will need to make an enclosure if you want it to look nice - it is designed to convert passive subs into active or as a replacement for failed amps so doesn't have an enclosure other than a plastic box and a metal front face plate.
If you don't opt for a Buttkicker, your options with the shakers if you live in the UK and don't want to import the Aura Pro from America are limited to the Sinus Live Bass Pump 3(£20), the Reckhorn BS100 (£45)(from the Shaker Centre) or the Sinus live Big Bass Pumping (£40 from Conrad).
The suggested amp will power 2 Aura Pros, or 2 Bass Pump 3's, or 1 Reckhorn BS100 or 1 Big Bass Pumping.
You will need to isolate your rig with rubber feet - the Penn Elcom 9106 is the best low cost option ($1.60). I am trying to get relatives to bring me a box of those from the USA. I used solid rubber door stops which are 1 inch diameter and 1 inch high (£1 from local hardware shop).
The Bass Pump 3's are supplied with 3 mounting screws with spring washers. These are ok when mounting onto wood, but they are better mounted using 3 M4 countersunk bolts with Nylok nuts and mudguard washers. You will also need speaker cable - I used 1.5mm 2x130 strand (anything bigger might not fit) - plus twin male RCA cable to go from the PS3 multiout to the amp or a Y splitter and male RCA cable if going from the LFE out shared with your subwoofer - try each and see which gives the best effect!.
Must get back to work desperately trying to finish my 3 channel shaker system in time for Christmas and repair the dining furniture in time for the big feast
