My LDPG cost I bought the following in July 2010. Flow Center Products: Two (I bought a spare) 1/8" gauge adapter GA125 = $22.22 ($11.11 x 2) Shipping was $12.66. From Dwyer: Pressure gauge DPGW-08 - $89.00 Stainless steel pressure snubber PS222 - $22.25 Shipping was $12.50 total for both Dwyer items. Total was $158.63 with shipping and an extra gauge adapter. You will need some Teflon tape to put it all together.
