For the number of years, time and effort Suthin invested in these trees, the prices are quite reasonable.
I am definitely thinking about one. But don't know if I will follow through. Such a purchase would use up two or three years worth of my "bonsai budget". If anyone was paying attention, I have not been buying pots on 99 cent bonsai for quite a while, so I have saved up a little in my "bonsai bank account".
I am not wealthy by any means. My income is below the national median income for a family of 4. Actually I'm probably closer to the poverty line for a family of 4. But I live inside my means, carry little or no credit card debt. I drive a 20 year old auto, which I need to replace soon. I will probably buy a 5 to 10 year old car and drive it another 10 years.
If found quite a while ago that buying lots of "cheap nursery projects" really adds up over a year. And all those "nursery projects" were taking up time and space that could go for fewer, but better trees.
Really, once you get to the point where you don't feel the need to buy another $10 juniper on sale at the local nursery, you can save up for better trees. I used to spend $20 to $50 a month on cheap trees, and about the same amount on booze. I quit buying cheap trees, quit drinking and my "mad money" account became my "buying better bonsai" account. It means once a year I can make a $200 to $500 purchase. And I did not make a purchase in 2020, so I am thinking about a purchase from Suthin. Though I should probably upgrade the auto first.
Seriously, once you have "learned bonsai" enough that the horticulture is not a limit, it is possible to focus how you buy, and even on a limited income, you can save up for better purchases. Better trees take more time to maintain. Detail wiring takes a lot of time, sometimes a whole day or more. One does not need many better trees to keep yourself busy.
I can do all the bonsai techniques possible on 100 sticks in pots in less than 100 minutes. Really, either a quick chop or one twist of wire, and you're done for another year. One the other hand, a $500 satsuki or JBP might need 4 or more hours of detail work two or three times a year. You don't need as many of these better trees to fill your time. The danger is your cheap sticks in pots will distract you from putting proper care into your better trees.
SO once you are confident about keeping a tree alive, and have a basic idea about how to train a tree, stop buying nursery stock, and start picking up older, closer to exhibition quality trees. But only use money that you would normally use on a hobby. Instead to constantly dropping $5, $10 or $20 every month, stash it away, build up a reserve. Make fewer but better targeted purchases. And start thinking about selling or gifting away some of your "sticks in pots" that you are not as interested in.
