I tried Vector Vest for 5 weeks paying $9.95.
My observations are :
They have an excellent data base and comes out with very good analytical tool with buy/sell or hold. The readings are often conservative and IMO it is your call and strategy to accept the call or make your own call. Nevertheless analysis is factual and make your own judgement.
Their buy/sell / hold recommendations are however very dynamic. I have bought ISF based on their buy recommendation just to find out the recommendation and stock listing disappeared from their data base
Having said that I bought TNE on their recommendation and encashed the dividend gain for a short term hold.
They do reply your emails seriously (not like Alan Kohler, Charlie Aitken, Marcus P or Small Cap I where it is the sales guy who fields your queries or never responds at all).
They run apparently free seminars at Brisbane, Sydne and Melbourne.

No one cares for Perth except Labour Government to suck the tax from hard working miners like me

IMO $9.95 is less than an MYO Lunch with drink and salad and less than a pint of Belgian beer in a pub

. So it is best to fill curiosity with a trial run and judge yourself.
