Block Heater for '01 BH

[MR.6690]

Looking to pick up a Block Heater to put on my '01 BH . Wasn't sure if I should just pick it up through the dealer or if there was a cheaper alternative/somewhere else to find one. Also, what is involved in Installation? doesn't seem to intensive. I've seen acouple on ebay but they've been for 05-07 Outbacks so not sure if they'd work seeing as theyre kinda newer gen.

They're all the same except for the Tribeca.
