Yes, absolutely, positively and definitely worth it. As many will mention, you only need it to protect you once and you could save thousands of $$ in damage.
The Surge Guard 34730 has now been superceded by model 34830. CW is probably blowing out the 34730 to make room for the new one. The 34730 is currently over $200 at all the other online RV parts vendors. CW has the new 34830 priced at $280. The new 34830 has open ground protection but the old one doesn't.
Technically the PI EMS-PT30C has better and more features vs 34730. Perusing the specs between the two, some of the differences I note are:
1. cuts out at 104V as opposed to 102V (104 is better).
2. 60 Hz frequency protection (good for generator use). The 34730 doesn't have this feature. .
3. 44,000 peak surge current vs. 6500 amps.
4. accidental 240 volt protection vs. 34730 which does not have this feature. The 34730 is permanently damaged on 240 volt.
5. on reverse polarity, the PI shuts down but 34730 does not.
6. has surge indication while 34730 doesn't.
As mentioned, Progressive Industries units have a lifetime warranty which is a HUGE plus. Some have reported a short life span of the Surge Guard unit. PI is made in the US, but Surge Guard is made offshore. A hardwired EMS is preferable so it won't grow legs and walk away, or get damaged.
I forbid you to buy the Surge Guard 34730 and insist that you get the Progressive Industries EMS-PT30C! :B CW has the EMS-PT30C
on sale for $299.99 incl. shipping but is $244.97 (free sh.) at dyersonline.com.
You can get the PI EMS-LCHW30 hardwired EMS at CW for $244.99 or $214.97 at dyersonline.com. The remote display is nice to have and you can currently get the EMS-HW30C for $233.45 at RVupgrades.com or from CW "on sale" for $284.99.
