I'd say Cabela's :

Garmin Echomap UHD 93sv (w/gt54 tdx) - $700
LVS34/GLS10 - $1,700

Now, that's if you want the Garmin transducer ... You might find the same unit w/o the tdx for less.

Just for clarity - I have a 93sv/LVS32 bundle that I paid $2200 for a few years back & that was without the Garmin transducer & a Crappie.com member discount. The Cabela's bundle is only $200 more, plus you still get the Garmin tdx. (I didn't want or need the Garmin tdx, as I already had a Hook 7 with its tdx on the trolling motor)

That being said .... I personally don't think the LVS34 tdx is worth the extra $$$, unless you're fishing VERY deep & need to spot fish/cover at great distances. But, that's just me (& no, I have not fished with the LVS34 tdx).
