Third choice
I don't think there's room in your boat for a Tecma...nor do I think it's appropriate choice for any sailboat under about 40'. It's an excellent choice for a trawler, but it draws too much power for a 34' sailboat...and the weight of any all china bowl & pedestal is likely to affect your boat's trim. IMO, the Raritan SeaEra is the best choice for a 34' sailboat. No...it doesn't look "like the one at home"...but nothing else on a sailboat does either. However, the pressurized flush water version is quieter than most household toilets...only draws 10 amps...uses only a .5 gal flush water...is LOT more durable than anything Jabsco makes...and costs < $400 if you know where to shop (i.e. anywhere BUT WM). These folks have the best price I've found: http://www.boatfix.com/elec/rartoi.asp
