I have used the VHC-1 for my QSK system and they work fine.

Subject: [TowerTalk] Greenstone vacuum relays
Does anyone have experience with products by Greenstone, especially the
vacuum relays:
http://www.greenstoneusa.com/vacuumrelays.htm
They are supposedly made in China and cost several time less than say
Jennings, etc..
They are sold by for example RF Parts:
http://www.rfparts.com/relays/relays-vacuum.html?p=2
and MAX-GAIN:
http://www.mgs4u.com/RF-Microwave/vacuum-relays-SPDT.htm
VC-2 sells for less than USD 100 while equivalent Jennings is over USD 300.
Worth taking a risk?
And then there is this special offer for hams by Gigavac:
http://www.gigavac.com/catalog/amateur-radio.html
Anyone tried those relays?
