Just another perspective...
My babies never ate pureed foods. Babies don't actually need that stuff, it's a consumer sucka thing that a lot of people fall for. Yes, even if you make your own. We pretty much followed the "until they are one, food is just for fun." My kids got most of their necessary nutrients and calories from nursing. Don't get me wrong, they were both trying out new foods from 6-12 months in addition to nursing. But baby foods really aren't a necessary step in their journey from baby to regular ol' person.
You can read about baby-led weaning if you want to try it out. (This is what it is called, it doesn't just mean letting your child's need dictate whether or not you continue to breastfeed, which is what weaning means in the US. In the UK, where latest iteration of the approach is based out of, weaning means adding complementary foods. I say latest iteration, because "baby food" really was an invention at some point in our recent history.)
Basically the approach is whole safe foods. And it is super simple. And your kid feeds him/herself foods that are safe, learning to pace themselves and listen to their body. I for sure would eat more if someone just kept spooning stuff I didn't even need to chew in my mouth until they decided I was done. Babies aren't that different.
For instance, I'd give my baby w/ two teeth a whole apple that I'd sliced a 1/2 inch piece off. She gnaws and gets to experience the taste, and more importantly, the texture. There's no choking hazard because the apple's as big as her face, and all she can get is little bits she can scrape off with two teeth. She is busy for 30-45 minutes and I get to relax. (but really I'm looking on in delight, because it's pretty darn cute...) When she started to show mastery of the pincer grip, I was able to chop soft fruits up - like peaches and plums, skins on, and put them in front of her and she'd have a grand time coordinating picking them up and eating them up! No need for special silicone coated soft spoons, purees, little containers, all the prep, freezing, etc. Just whole foods in a safe format, and self feeding.
Apparently this leads to non-picky eaters, too. Because pureed foods are all the same consistency, and kids need to get used to textures, not just flavors. IDK if that is true or not, but I do have to say, I have the un-fussiest eaters of any mom I know. My older kid's first year in preschool, the lunch lady told me Maile had such "continental tastes!" My kids aren't stuck on mac and cheese and chicken nuggets like a lot of kids. They love a good salad and eat all sorts of veggies. Greens, radish, eggplant, turnips, etc. Sure, they love a good mac and cheese. But I can make it half pasta and half assorted chopped veggies, and they will devour it. And the first thing my then two year old would ask for when we sat down for sushi was "'sabi! 'sabi!" Yeah, my two year old liked wasabi.
Anyway, I understand some people think this approach is wacky. That's fine if it's not for you and you want to do purees. Just thought I'd throw it out there! Good luck!
I also wouldn't get anything special. Just use your blender. Or a food mill, potato ricer, fork, etc. It doesn't need to be too fancy.
