I have no problem with a user taking photos and showing there accomplishments of sets they've purchased, especially when that is a set they have recommended numerous times to other members. I do also agree its best to start early on these sets so you do have the time to build them up before they do disappear.
I do have a problem with the second half of the statement basically belittling people for there choices of going and looking for the deals at Wal-Mart, Target. I for one enjoy going and so does my family. We plan weekend trips all around the southeast and stop in a lot of the stores on the way. Its a great way to break up the drive and walk around a little and possibly make some money at the same time. Theres a lot more to this hobby then just the investing part of which most of us are still collectors. The best run yet was when my daughter found the Vampyre Hearse and Mad Scientist to go with her Haunted House! The smile on her face makes it much more worthwhile then any of the money I make on Lego.
Everyone has there owns strategies, budgets, and methods of Lego investing. Theres plenty of small and originally populated sets out there that aren't exclusives that have made a lot of money and gone double and triple value so to say one set is better than the other and only stock up on those sets is kind of pointless. Sure exclusive sets do well for the most part but they also are the trickiest to build up without getting banned. It could be argued the time going to all the websites and compiling all the discounts to get these sets in quantity just as "wasteful" management of time as driving around to stores. Only difference is you don't use gas. It all is work, time, energy, and money and however one wants to do it is there business.
It goes back to thinking before you speak on the internet. The whole bottom of the post was just not called for. Most everyone is on this site with a similar goal of making money. How each person does it is up to them. Its fine to give advice which lots of members do but to generalize that if people don't do what you say then basically blast them on a public forum is not what the site is designed for.
I've had a good time on this site and its nice to be able to give advice and receive it on a daily basis. There just is no reason to put people down.
