Yes guys, please keep this civil!

I am learning quite a bit from this conversation about some things I previously knew very little about.
I used to be dead-set against using smileys, too. But then there was the one time I almost ruined a good friendship because the other person didn't know I was being sarcastic, and then my subsequent attempts at explaining myself ony kept getting misinterpreted even further. She politely suggested to use smileys in the future, and ever since then, I've been converted:mrgreen:
Now, back to advertizing. If I had a small upstart company selling model train items, I am not sure how I would go about letting people know. Suppose I bought equipment for casting small parts, and I decided to try and cast some detail parts for sale. I suppose I could throw them on ebay, and my "advertizing" is the ebay search.
Given some people's wariness towards ebay, my next options would be 1) try to get a LHS owner to stock them on consignment or sell them outright. The target audience here is whoever comes into the LHS and is willing to browse the racks. 2) I could start my own website, and maybe have it pop up when people search on google. 3) I could run an ad someplace directing people to my website.
Now on to #3... How long does an ad need to run for? I don't know about prices for print ads in magazines, or prices on other websites. But If I decide I just want to "test the waters", 35 bucks to run an ad for a week just to see what happens is not a big investment. If I had just started trying to sell stuff, and had just constructed my website, that's what I would do. I'd pay for a week, and if it brought in business, I would then consider putting up a longer-running ad somewhere else.
